A Japanese sun-powered car won the World Solar Challenge on Wednesday after averaging speeds of more than 62 miles (100 kilometres) per hour in a four-day race through Australia's desert Outback. "Organizers said the Tokai Challenger crossed the finish line in Adelaide, South Australia, at 3:39 pm local time, after 29 hours and 49 minutes' racing following Sunday's departure from the northern city of Darwin. The futuristic Tokai put in a near-flawless run with only one flat tire on the 3,000 kilometre race. Its nearest rivals were more than two hours behind and were due to battle it out for second place on Thursday," reports AFP.
